Two-phase flow measurements by nuclear magnetic resonance (NMR). Final technical report, January 1, 1993--September 30, 1997

Researchers pioneered NMR studies of concentrated suspensions starting in the late 1980`s (Majors, et al., 1989; Altobelli, et al., 1991; Abbott, et al., 1991). In those studies, they measured concentration and velocity of the liquid component either in pipe or Couette flow. If one compares these early studies of suspensions with more recent ones, imaging time has gone from 40 minutes to 8 minutes and the imaging matrix has increased from 32 x 32 to 128 x 128. In the interim, many concentrated suspension flows in both pipe and Couette geometries, with different particle sizes and shapes, and different kinds of liquids have been performed. The author summarizes the main results here and lists the publications that emanated from this grant.
